What are reliable sources for local community events beyond the town site?

[EllaYJ]

I'm new to the area and trying to get more involved, but I'm finding it surprisingly difficult to discover local community events beyond what's on the town's basic website. I'm interested in everything from library book clubs and park clean-ups to small art shows and neighborhood meetings. For long-time residents, what are the best, less-obvious ways you stay informed about what's happening? Do you rely on specific social media groups, neighborhood newsletters, physical bulletin boards in certain cafes, or word of mouth? I'd love to know which sources you've found most reliable for getting a genuine feel for the community's pulse and finding events that welcome newcomers.
